SAID NOVICK ASSIGNOR TO SAID YOUNG- AUTOMATIC CLOSURE FOR PORTABLE RECEPTACLES Application filed February 28, 1927; Serial No. 171,578.

This invention relates to means for sealing aportable reservoir such as an oil barrel and to automatically operated means to permanently seal said receptacle from the reinsertl, tion of a .withdrawal pump when the pump has been removed therefrom.

In the commercial world dealing with the sale of large quantities of fluids such as for example the sale of lubricating oil in drums,

l it has been the practice of the producing companies toucharacterize their containers with appropriate advertising marks in order that the purchaser was fullyaware of. the product that he was buying and also that the dealer would be able to guarantee to the consumer that the oil from that certain drum was as advertised.

It is the practice of some of these companies however, to discard and not refill the drums after they have once been used; This has been necessary'as an economical measure because the expense of reshipping the drum to a distribution point to be cleaned, 'reshaped, repainted and refilled would involve more than the cost of manufacturing new drums. Consequently, with no return of the old drum, they have accumulated among the retail dealers who, with questionable integrity, have too frequently refilled them with any variety of oil that was offered and then reinserted the pump to continue dispensing the bogus oil. It can be readily'understood that an empty oil drum with some well known producing companys name thereon, is a highly desirable medium to transport oil and if an inferior grade at a much lower price can be purchased for sale to an unsuspecting public as a better grade at a standard price, the unscrupulous agent is the beneficiary to the loss of the public who gets an inferior oil and to the loss of the producing company, who loses the publics goodwill,

a highly valuable asset, and furthermore loses the profit on the sale of its own oil.

However, if a means is provided to prevent a reinsertion of the pump, even though the receptacle may be refilled, the refilled receptacle is obviously of no material use for the attendant difficulty attached to removinga tion 40f the bung quantity of oil for example, without a, pump, is considerable.

It is therefore the principal object of our invention to provide a relatively inexpensive automatically operated sealing device which is to be incorporated into such a receptacle so that after the material is withdrawn and the pump removed, no pump can be reinserted.

It is a further object of this invention to provide a sealing means for. portable receptacles which will be operated by the removal of the withdrawal pump from the receptacle.

It is a further object of this invention to provide an inexpensive bung seal for a portv able receptacle to render it impossible to re- 1 insert a pump after the first insertion.

Other advantages and objects of the invention will appear as the description of the following drawings proceeds and, in which,

Figure 1 is a vertical section through our improved bung seal. I

Figure 2 is a plan view of the seal shown in Figure 1. r o V Figure 3 is a sectional view on the line 38 of Figure 2 showing the details of the slide'valve, g j

The portable receptacle partially shown as a metallic drum lis adapted to have the improved automatic bung seal 2. integrally attached to it, on the inside as by welding and is provided with the bung opening 3 corresponding with the screw threaded porseal 2, into which the pump (not shown) is mounted. The bung seal also has a reduced portion 5 that guides the stem of a suction pump 20, and a shoul der 6 serving to retain the metallic cup 7 temporarily in position. I r

Integral with the side and bottom of the sealing means 2 is a rectangular flange 8 with inturned lips 9 forming a grooved track for the movable slide 10 which is resiliently forced to the closure position by means ofa spring 11, snapped over the end of the plate 10 and attached to a vertical outwardly projecting boss 12 on the side of the bung seal 2. Any convenient attachment may be made although a pivot with the retaining cotter key is shown for purposes of illustration.

Within the boss 12, is a cylindricalbore 100 provided with a movable pin 14 urged downward against the slidable plate 10 by means of a resilient spring 15.

The operation of the device is as follows: If the cup 7 is forced out of retaining engagement with the plate 10 by the coaction of the stem of the pump 20, the plate, under resiilent pressure of the spring 11, will be forced into closure position as shown in dotted lines in Figure 1. Then, the plate portion in contact with the lower end of pin 14 being removed, the pin ltis forced downward by the spring 15 until it contacts with a depressed portion of the plate 10 and abuts the vertical portion 10a and thus securely holds the plate in a closure position from which the plate can not be removed.

It is the intent of this invention to contemplate the use of the pump 20 to remove the contents of the drum and which pump will be provided with an intake pipe extending into the liquid to be removed, and which pipe will immediately remove the cup 7 from its position of retaining the slidable late 10 to some other position in the receptac e. The pump intake pipe then occupies the entire space of the opening andit in turn prevents the slide from shifting. However, as soon as the fluid is removed and the pump withdrawn from the receptacle, no contact is had with the edge of the plate 10 and it is immediately forced shut and simultaneously locked.

The downwardly bent flange portion of the slide 10 allows removal of a. pump whose intake pipe will act on the bent portion to force the slide to the right as shown in Figure 1 to allow withdrawal without interference.

' It will thus be seen that we have provided a simple, elfective, inexpensive lock for a hung seal that will automatically operate under the certain conditions described and which will be impossible to reopen to allow reinsertion of a pump or other withdrawal means. It is, of such nature that it may be integrally attached to the interior of the drum during itsconstruction and when the drum is discarded, no great loss-will occur.

However, it is our intention to illustrate one form of embodiment of this invention, and'we have therefore shown one form which is illustrative rather than restrictive and we do not wish to be limited except as in the scope of the appended claims.

\Ve claim:
